Patent GB-119647-A (GB)
Title: An Improved Process for Isolating of Purifying Alkali Chromates.
IPC: C01G37/14
Filed: 1918-01-25
Abstract: 119,647. Soc. Industrielle de Produits Chimiques. Aug. 2, 1917, [Convention date]. Alkali chromates.-Crude alkali chromates, or alkali chromate fusion products, with or without the addition of a reagent such as chalk, and in presence or absence of water, are freed from alkali hydrates by extracting the hydrates with an organic solvent such as ethyl or methyl alcohol or acetone, which is afterwards distilled off. Any alkali ferrite present may be destroyed by the action of steam before or after the treatment with the solvent. Alkali hydrates, carbonates, aluminates, or silicates are removed from the chromates by the action of carbonic acid, in presence or absence of water, the products of decomposition of the impurities being insoluble while the chromates are unchanged. It is stated that the two treatments may be combined. Specification 138,111 is referred to.

Abstract: 647,802. Rope-making machines. HALL'S BARTON ROPERY CO., Ltd., and HACKETT, J. A. Jan. 22, 1948. No. 2039. [Class 109] In rope making machinery of the type in which a number of strands to be twisted together are brought from a rotating head in the form of a converging cone into a die, the die takes the form of several freely rotatable wheels whose planes pass through the die centre and whose innermost points lie in a circle normal to the finished rope and of the diameter of the rope. In the form shown, the die-frame 12 is provided with radial slots 14 receiving radially adjustable yokes or stirrups 15 which carry the hubs and ball bearings of six freely rotatable wheels 16 arranged with their planes radiating from the axis of the finished rope. Each yoke or stirrup 15 has a corresponding radially adjustable screw 17, engaging cap 18 and lock-nut 19. Each wheel has peripheral chamfers 20 to allow the innermost faces 21 thereof to approach so closely as to form a die and the faces 21 are preferably made arcuate and concave in cross-section. To adapt the die to different gauges of rope, standard hubs and ball races are arranged to carry various sizes of annular rotary parts. The wheels 16 may be rotated positively such as by means of bevel gearing. In a modification, the die-frame. or a wheel holder within such a frame, is rotated bodily around the axis of the rope, preferably at a rate substantially the same as the rate of rotation of the strand-carrying head of the machine. The plane of each wheel may be slewed about a radial axis and the die-frame may be made in two parts, such as semi-cylinders, detachably secured together. The machines may be used for making wire and fibrous ropes of all kinds. Specifications 11042/84, 631/08. 21101/10, 296,941 and 303,851, [all in Class 109], are referred to.

A submersible craft with at least one driving motor has hollow tanks 2, 3 lying longitudinally alongside the hull and the two tanks are connected to one another by a centre piece 4 which carries part of a coupling releasable from inside the craft. If, while submerged, the tanks 2, 3 are damaged or cannot be blown due to lack of compressed air, they can be released by turning a hand wheel 24 and the hull 1 floats to the surface under its own buoyancy. Weights 17 which lie on the centre piece 4 swing downwards to give stability to the hull and each tank has a buoy 22 attached to assist recovery of the tanks. In another embodiment the releasable connection holding together the hull and centre piece with tanks is a pivoted coupling. The centre piece may also have bow and stern members which allow it to become an independent hydroplane on release.
Patent GB-971844-A (GB)
Title: Gas diffusion electrodes
IPC: H01M4/98
Filed: 1963-01-17
Abstract: A sintered gas diffusion electrode is made by pressing and sintering a catalytically active metal such as Ni, Co, Fe and Ag, coating the sintered body with a catalytically inactive metal such as Al, Mg, Zn and Si, alloying the inactive metal with the active metal and finally dissolving the alloy formed and the inactive metal. The sintered active metal may be coated by the thermal decomposition of a gaseous organic compound of the inactive metal such as aluminium triethyl, aluminium tripropyl, aluminium tri-iso-propyl, aluminium tributyl or aluminium tri-iso-butyl. The organic compound may be used in a carrier gas of hydrogen or argon. In an alternative method a powder mixture of the active and inactive metals is pressed and sintered below the melting point of the inactive metal then heated to above the melting point of the inactive metal to form the alloy which is then dissolved with potassium lye.  In an example Al powder is rinsed with an aqueous solution of a flux consisting of 15% Na3AlF6, 60% NaCl and 25% KCl, dried, screened to 5-30m  and mixed with Ni powder 20-80m  in a weight ratio of 1 : 10.  The mixture is pressed and sintered at 640  DEG C., heated to 725  DEG C. for alloying and finally treated with potassium lye.

Television.-In a television transmitter a plurality of recording-elements 44, 45, 46 are associated with one or more record elements 40, 41, 42 and a reading-device transmits signals corresponding to the records. Three sections of the picture to be transmitted are explored simultaneously and each set of resulting signals is recorded on the corresponding rotating disc 40, 41, or 42 by the respective magnetizing coil 44, 45, or 46. When the record 53 on the first disc, for example, is complete, the corresponding search coil 47, which is rotated at three times the speed of the disc, is connected in circuit and transmits the record which is erased by a wiping-out coil 50. Search coils 48, 49 are successively connected in circuit so that signals corresponding to the three sections can be transmitted over a single channel. At the receiving-station the operations occur in the opposite direction. According to modifications : a single disc is used with magnetizing coils spaced 60‹ apart and followed by one search coil and the disc is rotated so that the exploration is completed whilst the disc is rotating through 60‹ (Fig. 2, not shown); a single rotating disc is used with four magnetizing-coils spaced 90‹ apart and a single search coil is rotated at four times the speed of the disc (Fig. 3, not shown).

Filed: 1920-01-27
Abstract: 162,379. Bond, A. V. I. Jan. 27, 1920. Flexible-pull actuation; thermal switches.-Relates to burglar and like electric alarms of the kind in which a spring-controlled switch arm cooperates with a pair of contacts, the arm being normally kept in a neutral position by a stretched cord, and consists in winding the cord on a reel carried by the switch arm and arranged to be locked after it has been set for the required length of cord. The apparatus is adaptable as a fire alarm. Figs. 1 and 2 are front and side elevations of the appliance. A line g stretched across a window, door, &c. is passed through an eye n<1> and coiled round a reel h, the spindle g of which is mounted to slide in a longitudinal slot in an arm c. This arm is pivoted to the casing at its upper end b and a spring c<1> opposes the tension of the line q. The arm b is normally held in midposition, and is moved to the left by the spring c if the line is cut, and to the right if the line is pulled by opening the door &c. In order to give correct initial setting an extension arm n slidable longitudinally on the arm b has a lug n<3> which may be brought against an abutment p<1>. The line is then rendered taut by turning the reel h, and the reel together with the extension arm n is then moved upwards, so that the lug n<3> leaves the abutment p', and the reel spindle jams in inclined slots in the arm b. Movement of the arm b to right or left causes a lug on the plate m to engage contacts on a plate e attached to the back of the casing, completing the circuit of a bell or lamp, or actuating a relay to lock or unlock doors, operate a telephone call, or start or stop any kind of lighting or heating apparatus. To enable the apparatus to act also as a fire or temperature alarm, two pieces of cardboard cemented together by wax or other easily fusible compound may be interposed in the line q.
